Description

Emission, hand are thrown and the automatically-controlled multifunctional dry powder extinguisher

The utility model belongs to light extinguishing device technical field

Chinese patent CN89201491.1 discloses a kind of portable dry powder extinguisher; This patent mainly is made up of the gas generator of interior primer pipe and powder extinguishing agent and shell.It is characterized in that having around the gas generator cylinder 1～20 row totally 4～1600 jet pipes, the jet pipe formula of extending out that contracts in being, there is throat's section the centre, twists with the fingers the lead-in wire single channel or multichannel causes with oil.Chinese patent CN89208163.5 improves on this basis, mainly be with the difference of CN89201491.1: 1. the jet pipe number becomes totally 1～1500 of 0～30 row, the formula of extending out that contracts in the shape of jet pipe is not limited to also comprises unconventional nozzles such as taper, arc, two circular arcs.2. increased the temperature control initiating device, oil has been twisted with the fingers initiation become automatically controlled initiation.Above-mentioned patent is light, cost is lower.But because the filling of gunpowder is to concentrate in the generator chamber in the gas generator, gunpowder outwards sprays at cavity internal combustion formation gases at high pressure during work, causes the explosion and the high noisy of gas generator easily, makes unsafe factor increase; The concentrated filling of gunpowder simultaneously also makes the maximization of this technology and seriation be subjected to serious restriction.The quantity of jet pipe is many in addition, and little two is big in the middle of being, and general technology is difficult to realize; Will certainly reduce the practical value of this utility model.

Design of the present utility model provides a kind of portable extinguisher, makes it security and improves, the good manufacturability and the expansion scope of application.

That utility model is achieved in that is simplified, dry powder, gas generator, and all with at present prior art is identical for igniter.It is characterized in that: 1. the gunpowder in the gas generator cavity does not adopt the mode of loading of concentrating, but open several independent combustion chambers respectively according to the purposes of using and the weight of dry powder, gunpowder is separately loaded, and the combustion system of carrying out secondary cycle produces gases at high pressure, promotes dry powder.So both reduced high pressure and high noisy in the gas generator cavity, security is improved, and effective protection area that dry powder is sprayed obtains increasing.The gas generator cylinder around down do not establish jet pipe, and the air-flow spray slits more than 1 in generation, slit can be even width, also can be interior big outer little, the slit on the little or cavity of outer imperial palace is the big and middle little form of inside and outside wall.Slit can be a closed at both ends and middle logical form also can be the logical form of an end.If the logical form of an end in order to gain in strength, also can be around with reinforcement in the gas generator chamber, the cross section of reinforcement can be circular, bar shaped or other profiled-cross-section.

The utility model has the advantages that: at first adopt the mode of separately loading gunpowder and secondary cycle burning, many unsafe factors such as high pressure imbalance in the gas generator cavity of having avoided causing and high noisy because of gunpowder concentrated combustion.Tool is inferior when the range of application different needs increases dry powder weight, the problem that can also not need corresponding increase to cause security to reduce because of the weight of gunpowder.Thereby further opened up the range of application of portable fire-fighting appliance.Can not only settle, hand throws, and fire extinguisher can be added propeller, emitters such as empennage are thrown at a distance with launching tube, so just can be used for water surface ship, oil tank, oil-vapor pipe, the untouchable fire rescue of forest or the like personnel.Be that to adopt the design of gas spray slits at the gas generator cylinder be that technology capability is good, cost is low at last, under the logical situation of slit one end, can directly extract core rod out moulding.Even under the situation of leading in the middle of only, if adopt plastics, raw material such as nylon utilize powerful releasing process also can directly make the slit of profiled-cross-section as the gas generator cavity.Can save the complicated procedures of forming that irregularly-shaped hole is beaten in the road, back, cost is reduced significantly.

Now that description of drawings is as follows:

Fig. 1 settles hand to throw the profile of embodiment for utility model is a kind of.

Fig. 2 is the A-A profile of Fig. 1.

But Fig. 3 is the profile of a kind of emission-type embodiment of utility model.

Fig. 4 is the gas generator profile.

Fig. 5 is the B-B profile of Fig. 4.

Fig. 6 is the profile of nut.

Fig. 7 is the outline drawing of gas generator cavity around last reinforcement.

Wherein: 1. simplified, 2. powder extinguishing agent, 3. gas generator cavity, 4. ignitron, 5. second-time burning pipe, 6. air-flow spray slits, 7. ignition charge, 8. hole for ignition, 9. ignite lead, 10. sealed colloid, 11. power supply, 12. hooks, 13. fire perceiving devices, 14. ends, sat, 15. dividing plates, 16. gunpowder, 17. strikers, 18. bodies, 19. burst line, and 20. emissions are sat, 21. propellant 22. vents, 23. pistons, 24. force pipes, 25. push rods, 26. empennage, 27. emission igniter cords, 28. nuts, 29. reinforcements.

The lead of igniting [9] of accompanying drawing 1 can be one or more, can hand throws fire extinguishing and also can place, and the employing of hook [12] can also be hung use, and fire perceiving device [13] can be various ways such as temperature control, light-operated, cigarette control.

Body in the accompanying drawing 3 [18] is the dry powder extinguisher part that has adopted in the accompanying drawing 1, and fire extinguisher and emission seat [20], force pipe [24], flight empennage [26] are combined, and utilizes launching tube, just can throw to the scene of fire at a distance.Because of safe and reliable, fire extinguishing power is strong, and with low cost.Can be as one of effective means of putting out a fire of professional fire fighter.Its novelty and practicality are all very strong.
